How to turn off the airbag light on the dashboard on a audi A3 2002 diesel

AIRBAG LIGHT WILL STILL STAY ON.TEST DRIVE WILL TURN UR ESP LIGHT OFF. THE TRIANGLE LIGHT AS U MENYIONED.LET ME KNOW .........

"Retriger airbag control unit"??? NOT! If the airbags are deployed in a 2000 Audi A4, the airbag control unit MUST be replaced. Pleases refer to 2000 Audi A4 service information for more details.

First of all you should access the Airbag ECU (Electronic Control Module) using suitable diagnostic equipment (VAS, VAG-COM) connected to the data link connector of the car in order to erase all faults - DTC's (Diagnostic Trouble Code) memored, unlock and reset the Airbag ECU. Then the Airbag light will turn OFF after approx. 4 seconds, ignition ON.
Good Luck!

I did not catch that it was a Diesel the first time. I had a Volvo with a VW/Audi Diesel at one time and it had a similar light for the glow plugs (the cylinder heater plugs). It came on momentarily when the key was first turned, but before starting the car. It would then go out when the cylinders were at the temperature to start the car, and I could then turn the key the rest of the way to start the car. Could this be it? They often do not come on in warm weather when they are not needed.
As far as determining which lamps are out, the easiest way is to have a friend walk around the car while you turn the different lights on and off, including the brakes and the turn signals. In the evening when you are parked, check the dashboard and the heater and radio controls to make sure that they are all lit, including the transmission indicator (PRNDL...). .Also, the lamp-out light can come one if a lamp is not fully into the socket, but you would notice a flicker then and not a steady light.

Always when you want to remove the battery by sure that the ignition key is in OFF position nad wait for least 3 minutes!
Now, for turning OFF your Airbag light you must connect a diagnosis scantool to the data link connector of the car in order to access the Airbag ECU (Electronic Control Unit) and erase all faults memored, in other words reset the Airbag ECU. Then the Airbag light will turns OFF.

Loose connector at back of dash.

a common fault on many cars is a dodgy yellow connector under the passenger or driver seat.

just push together tightly

worth checking

hi there should be a lock barrel somewhere in the front of the carit will be eithe rin the glove box, on the side of the dashboard on the passanger side, in the center console near the handbrake or to the lower right of thr steering wheel on the dashboard
with this you can use your car key to turn off the passanger air bag off (note- this will put the airbag light on)

hope this helps

You need access to VagCom (the diagnostic software from VW and Audi). You can download it free at www.ross-tech.com, and buy the interface cable for your laptop on eBay for about $20. Or you can pay an hour's labor at a VW/Audi dealer to have them turn off the light.

What probably happened is similar to what happened in my 99 Audi A4. I have side airbags in the seats, and if the front seats are moved all the way back for any reason, it puts tension on the yellow airbag connector under the seat. That pulls it out just enough to open the contact and trip an airbag failure light. What I did was zip-tie the connector tightly (be very careful of the wires, as they're small and you don't want to pinch them), then use VagCom to turn off the light. Using the software is the only way to turn the light off - no ignition cycling or drive cycles, or number of miles driven, nor a battery disconnect, can reset the light.

Use VagCom to find out which airbag is giving you trouble, zip-tie its connector, and have the light turned off. Then you're set.
